目的 探讨各种海绵窦区肿瘤的诊断特点以及伽玛刀放射外科治疗的作用。方法 本文回顾性地分析我中心 1994年至 2 0 0 0年底用Leksell伽玛刀治疗的 175例累及海绵窦肿瘤的临床材料 ,其中 90例 (5 1 4% )患者有开颅手术史 ;总结了各种肿瘤的鉴别诊断及伽玛刀治疗的经验。结果 本组 82 3%的病人随诊 1～ 84个月 ,平均 32 5个月。主要良性肿瘤的总有效控制率达 94 0 % ;3例因肿瘤再生长开颅手术治疗。伽玛刀治疗海绵窦转移瘤的近期疗效显著 ,患者平均 1年后的死因皆非海绵窦病灶所致。结论 伽玛刀可以作为海绵窦区小型良性肿瘤 ,或手术后残存肿瘤的主要的治疗手段 ;对已造成神经功能障碍的海绵窦区的转移瘤 ,伽玛刀也被认为是重要的综合治疗方法之一。
Objective To explore the diagnostic features of various cavernous sinus tumors and the role of gamma knife radiosurgery. Methods This retrospective analysis of our center from 1994 to 2000 by Leksell gamma knife treatment of 175 cases of cavernous sinus tumors involving the clinical materials, of which 90 patients (514%) had a history of craniotomy; Summary The differential diagnosis of various tumors and gamma knife treatment experience. Results 82 3% of the patients in this group were followed up for 1 to 84 months with an average of 32 5 months. The total effective rate of major benign tumors was 94 0%. Three patients underwent craniotomy for tumor regrowth. Gamma Knife treatment of cavernous sinus metastases significant effect of short-term, patients after an average of one year after the cavernous sinus lesions are caused. Conclusions Gamma knife can be used as a small benign tumor in cavernous sinus area or the main treatment of residual tumor after operation. Gamma knife is also considered as an important comprehensive treatment for metastatic tumors of the cavernous sinus area that have caused neurological dysfunction one.
